摘要
Generation efficiency of THz radiation in the skin layer of metal increases significantly when a nanolayer of dielectric is deposited on the metal surface. Additional amplification of the generation occurs if a weakly focused femtosecond pulse affects a structure where electron collision frequency in the metal is greater than the inverse duration of the pulse.
